| Effectively communicating key concepts of chemistry is important, especially when considering crucial, frequently seen topics. Language, definition and terminology play an important role in this process. Resonance, conjugation and hyperconjugation are topics that, in both general and organic chemistry, explain and predict a wide variety of phenomena. Past, current and suggested definitions and usage of these terms will be discussed. Since the first issuance of the term resonance, debate has ensued for how best to describe this important delocalization effect. Hyperconjugation has long been recognized as important, yet differences exist as to its relative importance in stabilizing reactive intermediates. Why are these topics defined as they are, and why are they introduced in the order in which they commonly appear? This lecture will address these issues and suggest a new model for communicating them. |
